Connection of stand-alone option unit
(2) Connection example with the FR-BR(-H) type resistor
Three-phase AC
power supply
Connect the inverter terminals (P/+ and N/-) and brake unit (FR-BU2) terminals so that their terminal names match with each other.
(Incorrect connection will damage the inverter and brake unit.)
When the power supply is 400V class, install a step-down transformer.
The wiring distance between the inverter, brake unit (FR-BU2) and resistor unit (FR-BR) should be within 5m each. Even when the
wiring is twisted, the cable length must not exceed 10m .
The contact between TH1 and TH2 is closed in the normal status and is open at a fault.
A jumper is connected across BUE and SD in the initial status.
NOTE
Do not remove the jumper across terminals P/+ and P1 except when connecting a DC reactor (FR-HEL).
